To work with Stability AI, I would recommend using mobile proxies. Also select the GEO proxy of the country where the service was created, in this case the USA. This will ensure stable connection and high performance.

Here's my personal top proxy picks.

Mobile proxies:

I buy mobile proxies from Soax, ShopProxy, Mobile Proxy Space.

IPv4 proxies:

For IPv4 it's advisable to buy individual ones to avoid blocks. You can purchase from Proxys.io (highly recommended! Perfect for AI stability), Proxy6, Proxymania.

IPv6 proxies:

I get IPv6 proxies from Proxyline and Proxys.io.

Residential proxies:

Residential can be purchased from Shifter, Proxys and Proxy Sale.

Additionally, I recommend using promo codes, which can be found here. If you still have questions about which proxies are suitable, feel free to write, and I'll answer if possible.
